I have a project where breakpoints worked well for .jsp included in other .jsp.
Recently, I have renamed all .jsp fragments to .jspf to avoid incorrect validation.

The problem is that now breakpoints are ignored in .jspf.
It strange because it supposed to be fixed byhttps://bugs.eclipse.org/bugs/show_bug.cgi?id=334150
However I can still "step into" an included jspf, if I put a breakpoint in the containing jsp page (before include).
